Title: Coin discriminator
IPC: G07D5/08
Filed: 1988-07-21
Granted: 1992-12-16
Abstract: A coin (5) under test is subjected to the changing magnetic field produced by pulsing of a test coil (1), and the decay of the resulting eddy currents in the coin is monitored by monitoring the coil voltage induced by the eddy currents. The times T1 and T2 at which the coil voltage falls through voltage levels V1 and V2 is measured by comparators (COMP 1, COMP 2) and a microcomputer (7), and those times are compared by microcomputer (7) with stored reference values to help determine the coin type.

Filed: 1988-01-29
Granted: 1991-04-03
Abstract: The invention relates to the tempering of sheets of glass and optionally their bending by the so-called contact process. It proposes a process in which the edge stresses of the glass sheets are reinforced by cooling the edges of the glass sheets in relation to their central zone, particularly by blowing on these edges with a cooling gas. It also proposes a device to perform this preferred cooling of the edges, as well as glass sheets thus tempered. The invention applies to the production of glazings having nonfragile edges, particularly for the automobile.

Date Nov. 30, 1989.An electric arc reactor having a substantially straight feed material passage extending through both the anode and the cathode. Gas is fed into the gap between the two electrodes so as to swirl about the axis of the feed passage and thereby confine the lateral extend of the arc and also confine the location at which the upstream arc root attaches to the upstream electrode. An enlargement of the passage in the gap end of the upstream electrode provides an internal sloping root attachment surface. A similar enlargement may be provided in the downstream electrode, but spaced from the gap, if the downstream electrode forms the cathode. Gas flow in a direction towards the upstream end of the feed passage is used to control the location at which an arc root attaches to the sloping surface of a passage enlargement. Magnetic means is provided to induce rotation of the arc such as to form a hollow arc column which is coaxial with the feed passage and through which feed material can pass.

Abstract: Condensateur céramique à semi-conducteur travaillant normalement comme condensateur d'absorption des bruits basse tension et des bruits haute fréquence, et comme varistor lorsqu'on lui applique des impulsions de haute tension ou des bruits d'électricité statique. Le matériau dont est constitué ce condensateur céramique est essentiellement du Sr(1-x)BaxTiO3, ce qui permet de cuire simultanément le matériau et l'électrode interne lors de la production. On décrit également un procédé de production de ce condensateur. A cet effet on ajoute un composant servant à transformer un matériau en semi-conducteur à une quantité excédentaire de Ti de Sr(1-x)BaxTiO3; on ajoute encore les composants Mn et Si qui se transforment en MnO2 et SiO2 respectivement pendant la cuisson, et l'on obtient aisément un semi-conducteur isolé par coupure de grain pour condensateurs, uniquement par réoxidation sans l'étape habituelle de diffusion en surface d'oxydes métalliques. En outre, selon l'invention, on calcine à l'air le comprimé après stratification pour obtenir un condensateur céramique stratifié présentant une fonction de varistor. Ce procédé permet d'éliminer dans la mesure du possible des désavantages tels que la rupture de l'électrode interne, le décollement interlaminaire, les fissures, la faible densité après frittage, et la non-homogénéité de la structure du corps fritté. Ce condensateur présente une remarquable amélioration de sa fiabilité et de ses caractéristiques électriques, telles que la capacité, la valeur de tension non linéaire exponentielle α et la tension de varistor.

Abstract: A sealing structure for an air preheater is provided for maintaining a constant clearance between the drum and deformable sector plates. Deflection governing struts or beams extend across the sector plates and bend in a manner which corresponds with the change in shape which the drum undergoes when its temperature changes. The outer ends of the struts are connected to an outer ring engaged with the drum via guides. As the drum deforms so that its ends assume approximately partial spherical curvatures in response to increased temperatures, the struts are likewise deformed. The deformation of the sector plates is controlled by the more rigid struts.
